I like them all, but not number 2, but maybe that one will work for your taste- it's just not mine. I really like 3 and 4 (the one your husband likes).

I think a larger black tone lantern would look great. You have only a single light box.. I wouldn't do three. I would personally do one or two decent size lanterns left and right. The size and width of the island would need to be known if you are hanging multiples. Many different lanterns out there in black. I favor the Darlana by Visual Comforts. It's very well made and has more straight lines than the mock up above. The iron on the one above across the top each piece is slightly rounded. This is Darlana however obviously showing in the gold tone. It's available in dark, gold and silver tone. With a lantern the ceilings will need to be fairly high.

The type of lighting that is typically on its own switch includes pendant lights and over sink lights. This allows for more control over the lighting in specific areas of the kitchen. In terms of combining lights, you can consider combining the under cabinet lighting with the pot lights to provide overall ambient lighting in the kitchen. The pendant lights over the seated counter can be combined with the over sink light to create a focused task lighting area for food preparation or other activities at the counter. For the room size of 10'x16', having 6 pot lights should provide adequate lighting coverage. For outlet locations, it is recommended to have outlets installed along the countertops for convenient use of small appliances. Additionally, consider adding outlets near the seated counter for charging devices or using small appliances while seated. Be sure to follow local electrical codes and regulations when determining outlet locations.

Typical distance from top of surface to underside of light is 30". I usually do 36" anywhere in a kitchen space.
